I just read through all 18 pages to make sure no one had posted it already, hopefully I didn't over look it. No one has mentioned the CUCV II. From what I've read they were basically Cheyenne trim level trucks with the military changes. All had a very unique brush guard and all have a 24 volt starting system. I can't find much on them, almost nothing. Some had 350s,454s, and the diesel. The few pictures on line I've found show them all with the diesel bumper but who knows what's under the hood. All of the ones I've seen pictures of were 8 lug, except the 2 door Tahoe like ones. They came in those, Suburban configurations and rclb from what I've found, including dually trucks as well. Some have ambulance beds. From what I read these trucks started production in 1996. I have never seen one in person, just the original CUCVs.
